The present invention relates to an attachment for application to adoughnut cutting and cooking machine, the purpose of the invention beingto form stick doughnuts of a banana formation, the

attachment comprising a divider or separator' to be positioned between astem centrally located within a doughnut forming tube, and the 1v/1h11of said tube, the lower marginal edge of the be to engage with ashoulder on the divider or separator to hold the divider in engagementwith a disc, between which and the lower marginal edge of the tube adoughnut may be extruded, whereby as the doughnut material such as doughis extruded from the tube and from between the lower marginal edge ofthe tube and a disc, the material may be divided, allowing the dough toassume an approximate formation of a banana. It is true that thedoughnut can be straightened out as much as possible if so desired, orit may be curved in any form.

' It is to be understood that the particulars herein given vare in noway limitative, and that while still keeping within the scope of theinvention, any desired modiiication of details and proportions may bemade in the commotion of the appliance according to circumstances.

The invention comprises further features and combination of parts to behereinafter set forth, shown in the drawing and claimed.

In the drawingz- Figure 1 is a vertical sectional view through the lowerpart of a conventional type of doughnut forming machine, such as isdisclosed in the United States Letters Patent No. 1,492,542, and animproved divider or separator as applied with- -in the tube and betweenthe lower marginal edge of the tube and a disc spaced slightly below thelower edge of the tube.

Figure 2 is a vertical sectional view through the tube and also througha movable sleeve operatively and telescopically mounted on the tube forcutting the doughnut as it is extruded, the divider being shown insection between the tube and the stem.

Figure 3 is a cross sectional view on line L-J of Figure 2.

Figure 4 is a detailed view of the stick or banana shaped doughnut.

Referring to the drawing, I identifies a tube outlet at the lower end ofa conventional type of doughnut cooking and cutting machine identitiedgenerally by the letter a, and 2 is a cutting sleeve, which operatestelescopically on the outside of the tube I. The doughnut materialextrudes through the tube and discharges from its lower end betweensaidend and a disc I, which is detachably mounted by a screw l and a nut5 on the lower end of stem I, the upper part of the stem being supportedintegrally from a bridge or web 1 extending across the tube I. Thedoughnut cutting sleeve 2 is operated by means of a double armed yoke 'lwhich is operatively pivoted as identified at I, and the yoke 8 isoperated by a cam member III, which lies in the path of actuatingmembers not shown, but are employed in connection with the machine asdisclosed in the patent herein identified.

As the sleeve 2 moves down after .sumcient quantity of dough hasextruded from the tube I, the lower marginal cutting edge I I of thesleeve 2 will act to cut the doughnut from the main portion of dough inthe tube.

Positioned in the tube I, between the wall of the tube and the stem I isa divider or separator I2, which may be made of any suitable material,either metal or wood, and it has a shoulder I3, with which the lowerinwardly beveled edge of the tube I engages. The disc 3 is secured inplace on the stem, as previously stated by means of a screw 4 and a nuti. By removing the nut the disc may be detached, allowing the divider orseparator to be inserted in place. By constructing the divider with ashoulder and allowing the divider to engage down upon the disc, thedivider is held securely in position and against displacement. As thedough feeds down through the tube, it is divided at a point from withinthe tube to a point, where the divider is substantially ush with theedge of the disc at Il and the outer surface of the tube at Il, so thatthe sleeve when operated may pass down over the outer exposed edge I6 ofthe divider and thereby cut the dough to form the doughnut from the mainportion of the dough, that portion of the dough being cut having beendivided, so that as it falls into the boiling liquid and is cooked itwill assume the formation as in Figure 4, substantially banana shape.

In order to remove the divider, the nut B'can be detached and the discremoved, after which the divider can be withdrawn from the tube.

'I'he invention having been set forth. what is claimed is:

l. The combination with a doughnut cutting machine having an annularchannel in which the dough is shaped into ring form and means forforcing the dough through said channel, of means for radially splitting,the ring.

2. The combination with a doughnut cutting machine having an annularcharme] in which the dough is shaped into ring form and means 55 betweenthe lower edge of the tube and the disc and dividing the dough as it isextruded and out.

4. Aa an article of manufacture, a. divider for c doughnut cuttingmachine. 'comprising s divider body positioned. between the centralstemund dough extruding tube ot the machine and having a shouldered partinterposed between the disc on the lower endoi said stem and the loweredge of the tube for dividing the dough extruded i'rom the .lower end o!the tube.
